요약	The DQOL is a patient-reported measure of quality of life impact in people with diabetes. Developed by the Diabetes Control and Complications Trial (DCCT) Research Group in 1988, this 46-item questionnaire assesses how diabetes affects daily functioning, emotional well-being, worry about complications, and satisfaction with life and health. It is widely used in diabetes clinical trials and research to capture the burden of diabetes management and impact on psychosocial well-being.	The COPD Assessment Test (CAT) is a simple, rapid, patient-centered measure of COPD symptom burden and functional impact. Developed by Paul Jones and colleagues in 2009, this 8-item questionnaire captures how COPD affects cough, sputum, chest tightness, breathing difficulty, activity limitation, confidence, sleep, and energy. It is used worldwide in clinical practice to guide disease management decisions and as a primary outcome measure in COPD clinical trials.
